Figs. 21 and 22 are views illustrating a means for separating the paper sections.

Referring to the drawings, and particularly to Fig. 1 I show a machine of the class specified in which there are live heads or magazines A, B, C, D, and E, each onecont aining pile or stack of newspaper sections which are to be assembled to form complete newspapers. Head or magazine A contains a pile of papers which are to be outside or cover sections of the complete paper. Heads or magazines B, C, D and E contain papers which are to be inserted into the outside or cover section, one from each of said heads B, C, D and E into each outside or cover section. At F is a delivery mechanism by which the complete newspapers are delivered from the machine. As this delivery mechanism forms the subject matter of a separate application for patent executed by me of even date herewith, Serial No. 562,462, filed May 20th, 1922, the same will not be described in detail herein.

Extending along the heads A to E, inelusive, is a support G, which is preferably in the form of a V-shaped trough adapted to receive cover sections from the head A and to support the same in an open condition as they are moved along from head to head to receive insert sections from the heads Bto E, inclusive.

At each of the heads A to E, inclusive, there is a feeding mechanism by which paper sections are fed one by one from said heads to the receiving and supporting trough G. At the head A there is an opening mechanism by which the cover sections are opened. Advancing mechanism is provided for moving the open cover sections along the support G to receive the insert sections from heads B-E, inclusive, and to deliver the complete newspapers to delivery mechanism F. Along the support G there are various instrumentalities-for holding the cover sections open and also for moving each insert to one side of the open cover section so as to make room for and prevent interference with the next insert section. Other instrumentalities are provided for automatically stopping the machine when there is improper or imperfect operation, as for example, at one of the feed mechanisms. hen the machine is automatically stopped in this way the point where the trouble is, is automatically indicated.

In Fig. 1 I show an electric motor 1' mounted on the floor at the left hand end of the machine for driving the same. This is understood to be suitably connected with some source of electrical energy. This motor is provided with a pinion 2 meshing with a gear 3 on a shaft a on a pedestal 4 (Figure 2). Certain driving shafts are run by this gearing, as will be pointed out more fully hereafter.

The mechanism for feeding the cover sections from head A. to support G and opening them in said support is shown best in Figs. 1, 2, 3, 4, 5, 7, 8, 9, 10 and 11. In this arrango ment the head A is provided with front uprights 5 for holding the "front edges of the papers. Strips 6 support the pile of cover sections a arranged in this head A.

The cover sections a are fed from the head A by feeding apparatus adapted to engage the bottom cover section a and push same out of the bottom of head A. This feeding mechanism comprises a series of reciprocating sliding shoes or carriages 77 supported by the members 6-6, said shoes 7-7 being provided with means for first engaging a bottom paper section and pulling it backwardly to release its front end, and for then pushing it forwardly to eject it from the head. These paper engaging means comprise pivoted dogs 88 and 9-9, one dog 8 and three dogs 9 being associated and connected together to form a set. These dogs 8 and 9 are pivotally connected by pins 1010 with the shoe 7, and are provided with needles which engage the lowermost paper section. Dogs 99 are in front of dog 8. Dogs 8 are for engaging bottom paper section to withdraw or retract same a short distance to release the front end of the paper section from abutment 12. Dogs 9-9 are for engaging a paper section to then move it forward to eject it from head or holder. Shoe 7 has side projections 7 sliding in grooves G in members 6, holding shoes 7 in proper position and permitting their back and forth sliding movement. The particular feeding mechanism employed in the device is sub stantially identical with that shown and described in an application filed by me of even date herewith and will therefore not be explained in detail herein.

The sliding shoes 77 are reciprocated by links i pivotally connected with swinging arms 7 on a rock shaft 7, which is actuated by an arm 7 pivotally connected with a link 7 e which is in turn driven by a crank 7 on shaft 7 driven by gears 7, 7 and 7 from drive shaft 4, gear 7 being on main drive shaft 7 The feed devices for head A, feeding cover sections, are driven by shaft 7 actuated by feed drive shaft 7 The feed devices of the other heads B, C, etc. feeding in sert sections, are driven by separate shafts in alinement with shaft 7, but disconnected from same, said shafts being also driven from shaft 7 as' by links such as 7, similarly connected and arranged to link 7. These separate shafts are provided because of the need of feeding paper sections from the cover section head A. at time different from insert section heads B, C, etc, each cover section being fed prior to the feeding of an insert section, to permit opening of the cover section and movement to an insert head before an insert section is fed to it.

The outward movement of the paper sections from head A is aided by a belt 1 F traveling over wheels 15 and 16 mounted on shafts 17 and 18, respectively. The shaft 17 is driven intermittently by a ratchet arrangement consisting of a ratchet wheel on shaft 17, and a swinging arm 17 being actuated by link 19 pivoted to crank arm 20 on shaft 7.

The cover sections after leaving the head all) A pass between feed rolls and 21, the former of which is mounted on shaft 22 and the latter on a drive shaft 23, which is geared to front drive shaft 23 driven by gear 8 on shaft l, and extending clear across the front of the machine so as to drive feed rolls 20 and 21 for all the heads A, B, etc. The cover section being fed upon passing be tween the feetL rolls 20 and 21 strikes against a battle or abutment 24 by which it is turned downwardly so as to direct it into the support or trough G, in which as previously explained the assembling of the paper sections takes place.

The cover sections move downwardly to the bottom of the troughs or support G and when they reach the bottom of the same are instantly and automatically engaged so as to prevent them from rebounding upwardly The preferred form of mechanism for this purpose is generally similar to mechanism for the same purpose disclosed and claimed in my pending application Serial No. 406,578, filed April 28, 1920, newspaper stuffing ma chine. The mechanism shown comprises cooperating rollers 25 and 26, arranged near the bottom of the trough G and adapted to engagethe sides of the cover sheet when the same comes in position between tl em. The roller is driven by sprocket chain 2? which is in turn driven by shaft 28, Whirl latter is driven by sprocket chain running over sprocket wheel 80 on rotary shaft 28. Another feed roll 31 is arranged below the feed roll 21 and driven by a sprocket wheel 32 meshing with the chain 29, the-roll 31 further assisting the cover section in its down ward movement into the trough G. An idle sprocket 33 is arranged abovethe shaft 28 and mounted for adjustment to take up the slack in said chain 29. The roll 26 which cooperates with the driven roll 25 is mounted for swinging movement toward and away from the roll 25, as for example, by mounting said roll 26 on a swinging arm 35 pivoted at 36 and having a lever arm 37 which is pivotally connected with a reciprocating link 38. The link or rod 38 is reciprocated by a cam 39 engaging a roller 10 on said rod 38, the cam 39 driving the rod 88 positively in a forward manner so as to swing the roll 26 toward the roll 25 and a spring 4L1 being employed to swing or retract the arm 35 in the opposite direction. The movements of the rod 38 and arm 35 are so timed that the roll 26 is separated from the roll 25 when the cover sheet is descending into the trough G, but is moved into close proximity to roll 25 as the cover sleet approaches the bottom of the trough, so that when the lower edge of the cover sheet has nearly or quite reached the bottom of the trough, the rolls 25 and 26 are suliiciently close together to firmly grip and hold it, the movement of roll 25 being downward adjacent the cover section, so as to press same downwardly.

Further feeding devices, preferably in the form of feeding tapes are arranged to assist in feeding down thotrough. These tapes are e:" ndet over one side of the feed roll 20" an also over idle rolls 46 and at! on shafts i8 and 49, respectively, and also extended downwardly and around feed rolls 50 on a shaft 51. he shaft 4:9 is secured to the framework of the machine by bolts 52, 7), and the shafts 51 carrying rolls 50 are carried by arms pivotally mounted on shaft This permits rolls 50 to be swung upv by swinging arms 58, which arms are normally held downwardly by springs 5% on shaft As rolls 50 are opposite rolls 31, said rolls 50 are normally pressed toward rolls 31, and thereby nor- .ially pressed against the cover sheet and consequently assist in moving the same downwardly.

ld hen the cover section is in the trough G it is opened so that the insert sections may be the cover sheets 0; into and could be employed but as a preferred 1.. y I employ an opening mechanism having the general features of construction and operation of the opening mechanism il lnstrated and described in my aforesaid application Serial No. 920,184. By this mechanism the outer or far side of the cover section is buckled or crumpled downwardly, and then allowed to iso and upon rising passes on the outer side of an opening blade which thus occupies a place between the two sides of the cover section. The sides are then spread or separated by the action of this inserted blade and by further opening or separating mechanism.

This opening mechanism is shown in Figs.

S, 4-, 21 and 22. It comprises oppositely disposed heads 55 and 56, the former adapted to engage the inner side of the cover section and hold it in position and the latter adapted to engage the outer side of the same and push it down so as to buckle or crumple said outer side and then pull it up to original position, as a result of which operation an opening blade or insert member 57 will be located in position between the inner and outer sides of said cover section. The head 55 is carried by a reciprocating member 58 which latter is reciprocated by a cam 60 on a driving shaft 61, said cam 60 cooperating with a roller 62 on the reciprocating member 58. A hearing 63 is provided for head and another hearing 64; for enlargement 65 on the member The member 58 is jointed at 58 and has a rear section or extension 58 connected with the section 58 by sleeve 58 which encloses spring 58. Bolts 66 regulate the distance be tween members 58 and 58'. Shaft 61 is Various forms of opening mechadriven by main drive shaft 7 by means of gears 67 and 68.

The head 55 is provided with a device for engaging the adjacent ply of a cover section, said device comprising pins 69 set in a blocklike member 70 (Figs. 21 and 22), which latter is provided with a threaded bolt 71 en gaged by a nut T 2 to hold said member 70 in position in the head A collar 73 surrounds the outer end of the member 70 and fits loosely over the same so that it may be slid back and forth to cover and uncover the ends of the pins 69. Said collar 73 has a flange 71- adapted to fit in a recess 75, so that when pressed inwardly the flange 7 1 will fit into recesses 75, whereas when in an outward position the flange 7 1 cover said pins, as

shown in Fig. 21. A spring 7 6 is arranged in a recess surrounding the member 70 and acts against collar 73, tending to push the same normally in an outward direction. Thus as the head 55 is reciprecated, the flange 7% will be pushed against the adjacent fold of the cover section and will be slipped back on the member 70 so as to expose the pins 69 and thereby cause the latter to penetrate the cover section fold, as shown in Fig. 22. The other head 56 is also provided with paper engaging pins 77 on a member 78 which later is surrounded by a collar 79 having a flange 80, said collar being subject to a spring 81 tending to push the collar 79 normally out.

This head 56 is carried by mechanism by which it may be reciprocated in a more or less vertical manner so that after it has engaged the outer fold of the cover section, that is the fold nearest the head 56, said head may push said fold downwardly and buckle the same, as shown in Fig. 22. To such end said head 56 is carried by a reciprocating rod 88, by means of a connecting pin 8 The pin 84 slides in a slot 85 in a plate 86, which latter is mounted on an arm 8? pivoted at 88 so that the plate 86 and with it the head 56 may be swung in and out to bring the head 56 into cooperative relation with the head 55, and also to separate the head 56 from the head 55 by a substantial distance to permit access to the trough or support G at this point. The reciprocating rod 83 is connected at its upper end to a pivoted lever 89 pivoted on a shaft 90 (Fig. 6), which shaft 90 is rocked by suitable cain action so as to give the head 56 the necessary up and down reciprocation. Such cam ar angement comprises cams 91 and 92 on main. drive shaft 7 (Fig. 6). Cam 91 cooperates with roll 93 and cam 92 cooperates with roll These rolls 93 and 941 are carried by a rod or arm 95 having a pivotal connection 96 'ith a short rotary arm 97 on the shaft 90. Thus the reciprocation of the arm 95 in one direction and the other by cams 91 and 92 acting on rolls 93 and 9 respectively, causes a rocking of shaft 90 and the consequent swinging of arm 83 and reciprocation of head 56 to buckle the outer ply of cover section.

The outer ply or fold of the cover section being thus buckled, the head 56 thereupon moves upwardly and when so moved its upper end will pass outside of the plate 57, whereby the two plies are separated with the plate 57 between them. Plate 57 is mounted so that it hangs in a substantially vertical position, as shown in Fig. 3, its lower end being loose and its upper end being suspended upon a shaft 18 so that said plate may be swung into a substantially horizontal position if desired. A spring 57 normally holds the plate in vertical position.

The cover section being thus permanently opened, it is further opened by means of a nose or supplemental opening member 99 arranged in position in the trough G and located so that its end fits against the end or projection 57" of the insert member 57 (Fig. 7 This member 99 is adapted to further spread or separate and open the cover section as it is moved along the trouga, said member 99 extending len 'thwise of the supporting trough G, but being inclined toward the front of the machine, as shown in Fig. 9, whereby the rent or outer fold of the cover section will e moved or swung outwardly or forwardly as it moves lengthwise of the trough. Another member 100 forms a continuation of the nose member 99 and is similarly inclined, said member 100 extending well toward the forward side of the trough where it is secured upon a supporting member 101 (Fig. 5). The nose member 99 and the extension member 100 are preferably adapted to be swung out of the way so that access may be had to the interior of the trough if cesired. To such end the nose member 99 is hinged at 102 (Fig. 7'), so that it can swing crosswise of the trough. Also the member 100 is mounted so that it can swing by mounting the supporting arm 101 on a pivotal shaft 103 5), the latter being supported on a bracket 10a on the machine frame. Preferably the front wall of the trough G is made so that it can swing in sections forwardly so as to open or partially open the trough. To such end the outer section 105 of the trough (Fig. l) is mounted on a shaft 106 so that it can be swung backward and forward. Also the front wall section 107 is mounted so that it can be swung forwardly as by mounting it on bracket 108 supported on pivotal shaft 109, Fig. 5. Also other front wall trough sections 110, 111, and 112, (Fig. 1), are mounted for forward swinging opening motion in the same manner as section 107, as will be referred to more fully hereinafter.

Referring again now to the opening of the cover section by the members 99 and 100 and the movement of said section along the trough G, said movement occurs continually so as to bring said section in front of heads B, C, D

if b

and E in succession. When opposite head B another section of the paper which will be called the first insert section b, is inserted from said head B.

The insertion of such an insert a will be accomplished by feeding mechanism such as previously described in connection with head A. Such an insertion is shown in Fig. 5, the outer or cover section a being shown at the bottom of the supporting trough G, and the first insert section 6 arranged in the open cover section a.

As a preferred arrangement the first insert 7) is shifted to the inner side of the trough after it has been deposited therein, so that said first insert will be well at the inner side of the cover section when the latter is advanced sufficiently along the trough to come opposite the third head C. This permits another insert to be readily introduced into the outer or cover section without any interference with the first insert 5.

For this purpose, I show in Figs. 10 and 11 a longitudinally extending guide or plate member 115 which inclines or extends inwardly toward the inner side of the trough Gr so as to move the first insertin that direction. At a point opposite the head C the first insert Z) is well in toward the inner edge of the trough so that a second insert 0 may readily be deposited in the interior of the outer section a. Such an insert 0 is shown being deposited in the trough in Fig. 5. This insert 0, it will be understood, is fed down from the head C at an appropriate time when the cover section a containing the first insert 6 has been moved opposite or substantially opposite to said head. 7

It is also preferably arranged that this second insert 0 may be shifted to the other or outer side of the trough G to permit the ready introduction of a third insert cl from head D. To such end guide or plate member 116 extends along trough G and inclines forwardly or outwardly as shown at right of Fig. 10. Insert 0 strikes this and is rushed forwardly. This permits a third insert (Z from head D to be fed down. This will occur just as described for insert 0, the trough section in front of head D being constructed just as trough section in front of head C, whereby insert (Z is fed into cover section a in the same place as c is shown in said Fig. 10, insert 0 at such time being between guide member 100 and wall section 111 (similar to 110) having been pushed there by guide member 116 in trough in front of head C. p

The insert (Z is pushed to the front by guide member 116 in the trough section in front of head D, (Fig. 10), so that insert cl comes into position between 116 (Fig. 11) and front wall section 112, thereby making room for insertion of the final insert 6 from head E. Such an insert is made as shown in Fig. 5.

Thus the cover section a will contain the four inserts, Z), 0, (Z and e, whereof the first insert 7) is at the inner side of the cover section, and the other inserts 0, d and e are at the front or outer side of the cover section.

The cover section containing these four inserts is now closed, preparatory to delivery to the delivery mechanism of the machine. To such end another guide member 117 (Figs. 5 and 11) is provided, the same hav ing'its left hand end (Fig. 11) secured to the inner wall of the trough and being then extended or inclined forwardly. Thus the inner fold or ply of the cover section a will strike against the member 117 and with the first insert Z) will be pushed forwardly toward the other or front cover section and the three inserts 0, cl and e. The guide member 116 terminates before the member 117 terminates, thereby providing a relatively small space 118 between the end of member 117 and the end of front wall section 112. The complete paper, the cover section with all the inserts, is thus closed at said space 118 and then delivered to the delivery mechanism, which will be referred to more fully hereinafter.

In connection with the trough and guides therein, it may be noted that as a preferred arrangement the front wall sections 107, 110, 111 and 112 are as a preferred arrangement located respectively in front of the heads B, C, D and E, the joints being preferably about midway between the successive heads, and as previously pointed out these front wall sections are independently adjustable to permit an one or more of them to be swung forwardly so as to gain access to the interior of the trough. Also the various guide members such as 100, 100, 116 and 116*, are mounted on arms 101 supported by a shaft 103 so that they may be independently swung forwardly and upwardly to permit access to the interior of the trough. Thus any one of the several trough sections may be either partially opened by the forward or outward swinging of the corresponding wall section, or may be fully opened by swinging such wall section and also swinging the corresponding guide member. This permits ready access to either the front of the trough or the front and rear of the same at any desired point.

For advancing the cover section and inserts along the trough, I show a pair of chains 120 arranged on opposite sides of the trough as shown in Fig. 5,, and mounted on sprocket wheels 121 and 122 at the opposite ends of the machine. These chains are provided withinwardly extending projections or fingers 123 located at intervals and adapted to engage the rear edges of the cover sections and push the same along the trough. These sprocket wheels 122 are driven by sprocket chains 125 through the medium of a drive shaft 126 connected by sprocket and chain with shaft 126, which is connected by mitre gears 127 and 128 with another drive shaft 129 which is in turn gear connected with the main drive shaft 7*. The sprocket chains 120 advance continuously at such a speed as to move the cover sections forwardly to receive the various inserts and finally deliver the whole to the delivery mechanism.

Certain provisions are made for automatically stopping the machine in case there is improper operation in certain respects. For example, provision is made to automatically stop the machine if there is improper feeding from the first head so that two papers instead of one are fed from the same. This arrangement is shown in Figs. 3 and 13. The drive roller 20 is mounted so that it may have a certain amount of vertical adjustment, and when a paper goes through between rollers 20 and 21, 20 moves up a determined distance. A screw 135 is mounted above shaft 22 so that when the latter is raised higher than the determined distance it will contact with the lower end of screw 135. Screw 135 is mounted in a block or strip of insulation 136, preferably pivoted at 137 on a bracket 138, whereby screw 135 may be elevated slightly by an extent of movement on the part of the shaft 22 greater than is necessary merely to contact with end of screw 135. A conductor 139 runs to binding post 1 10 on insulation strip 136, and thence to another binding post 140 which also serves as a lock nut for screw 135 to hold the latter in adjustment, said screw 135 being provided with a knurled head 141 permitting it to be turned so as to adjust it 1n insulation strip or support 136. Conductor 139 runs to certain switching or annunciator mechanism as will be explained more fully hereafter. Suflice it here to say that undue elevation of roller 20 causes contact of the shaft 22 with screw 135, thereby closing electrical circuit through ground of the machine to conductor 138 running to switching and annunicator mechanism as will be described hereafter. This mechanism automatically opens the motor circuit and thereby stops the machine from running and the annunciator mechanism indicates the point where the trouble is so that it may be at once found when the machine is stopped. Two or more papers passing out of the first stack A will cause this elevation of shaft 22 and roller 20, and thereby cause this electrical stoppage and indication. To preventbreakage and allow plenty of play on the part of shaft 22, screw 135 is pivotally or otherwise adjustably mounted as described. To permit adjustment of the machine to different sized paper sections in stack A, screw 135 may be turned so that its end will be raised or lowered to permit more or less play on the part of roll 20 before contact is made with the end of said screw 135. This point of trouble is,

as noted, at the first stack A, which may be called for convenience trouble point G.

Another automatic stoppage of the machine and indication of point of trouble takes place when a paper from the first stack A feeds into the trough in a crumpled condition, so that it will not feed properly to the opening mechanism. This arrangement is best shown in Figs. 7 and 15. The swinging panel or trough wall member 105 is provided with a contact 147 conveniently formed by the outer end of a bracket 148 secured to bracket 1 19 on said wall member 105 by screw 150. A spring 151 on insulated end piece 152 is in position to be made contact with by contact 1 17 when wall member 105 is swung outwardly and this would take place when a paper in a crumpled or thickened condition was fed into the trough. hen contact is made between 147 and 151 the end 153 of spring 151 makes contact with screw 15st secured to but insulated from end piece 152, thereby closing the circuit between the ma chine or ground and contact 15st to which is connected wire 155 runi'iing to the aforesaid switching and annunciator mechanism, as will be presently described. This closure of the circuit between contacts 153 and 15% will automatically stop the machine and indicate where the trouble occurs, that is at this beginning end of the trough which we will call trouble point H.

Provision is made for stopping the machine when trouble occurs at the opening head, where the cover section is open to receive the insert sections. This is best shown in Figs. 6, 7 and 12. In this arrangement the opening member 99 is mounted for longitudinal movement in the trough when a cover section jams or is not properly opened. As a simple arrangement said member 99 is mounted upon a bracket member 157 which is pivoted at 102, Fig. 12, to another bracket member 158 which is in turn pivoted at 159. Thus the forward movement of the jammed or thickened paper section, or an improper opening of the same will move the member 99 lengthwise of the trough and this movement will cause an upright 160 (Fig. 6) on said member 99 to strike against a contact 161 arranged below and secured to an insulation strip 162. Actuation of the contact 161 will cause the same to strike against a contact screw 163 to which a conductor 16% is connected. Spring 165 tends to hold the member 99 in normal position but to allow the same to move by the jamming of an improperly operating paper section. The actuation of contact strip 161 so as to make contact with 163 will cause closing of circuit through con.- ductor 16 1 to the switching and annunciator mechanism, automatically stop the machine and also indicate the point where this trouble occurs which we will call trouble point I, opener mechanism trouble.

Another provision for stopping the machine in case of trouble is in case of improper feed at the stacks B, C, and E. In casethere is improper action at any one of these stacks, so that no paper section is fed from any one of the same, stoppage of the machine and indication of trouble takes place. The mechanism shown. for this purpose is best shown in Fig. 8, and comprises a swinging arm member 168 having a linger 169 which is arranged underneath a paper section in process of passing through feed rolls 20 and 21. The men her 168 is pivoted at 169 and provided with a bra cket member 170 to which a swinging arm or link 171 is pivotally connected at 172. Spring 173 is connected to arm 171 tending normally to hold said arm 171 and also bracket 170 in a downward position, thereby tending to force linger 169 upwardly against the feeding paper section. A bracket 17 1 of insulating material serves as a pivotal support for arm 171 and a contact 175 is arranged in position to be struck by end of arm 171 if said arm is pulled down suiiiciently by spring 173. Contact 175 is held in position by insulating block or strip 177, member 17 1 being also made of insulating material. Conductor 178 is connected with contact 175. Thus r ien a paper section as (Z, (Fig. 8), is being l ed between rolls 2O and 21, member 168 will l oe held down by said paper section so that arm 171. will not touch contact 175. When, however, no paper section is above upper end of linger 169, said finger is free to rise in response to action of spring 17 3 and arm 171 will make contact with contact 175, thus closing the circuit through the machine and conductor 178. This conductor runs to the switching and annunciator mechanism previously referred to wnich will cause the auto,

matic stoppage oi the machine and the indication of the present trouble. There are four mechai'iisms ot' the kind just referred to for automatically stopping the machine, said mechanisms being located at the stacks B, C, D and E, each one as well as stopping the machine will indicate where the trouble is. These trouble points will be called 5, J, J and J Provision is made for StOPPlDg the machine automatically in case of trouble at the delivery end, where delivery the paper is made to the delivery mechanism l Fig. 11.

This arrangement comprises a contact strip 180 on an end brac ct 181, and a Contact screw 1 2 adapted to be contacted with by the end of strip 180. This contact will take place when trough wall section 112 is suing outwardly by a jammed or crumpled paper screw 182 and cause the stoppage 0 machine as will be described hercinaiter, and the automatic indicatioi'i oi the point of trouble which will be called trouble point K, delivery end of the trough.

There is one further arrangement for automatically stopping the machine, and this is in case here is some interference with the machine bringing a heavy strain on the main driving shaft so that unless relieved the shaft itself or some gear connected with it might be broken. This arrangement permits the main body of the drive shaft 3 to be in effect separated from the motor and the electrical connection to be made to stop the motor when such separation is made.

This arrangement is best shown in Figs. 17, 18 and 19. in this arrangement the drive shaft 7 is ointed, as shown in Fig. 18, the main body part which is connected with the motor carrying a gear 185 in mesh with another .QGitl' 18-8 on shaft 129 which latter 6X- tends down through bevel gears 128 and 127 which drive the chains 120 for advancing the cover section and inserts along the trough. e supplen'iental bar or extension 8 of the a e shalt 7 is connected with the main part 7 by a pin 188 which is strong enough to impart movement from 7 to 8 ordinarily, but isweak enough to break in case an excessive strain is put on 3. In case of breairage of pin 188 of course shaft will turn relatively to Electrical connection is provided to antomatically stop the motor and indicate the place of trouble, which in this instance will be called trouble point L, main drive shaft.

As a convenient form oi" electrical connection, I show a pin 189 in a slot in a head 190 on shaft 8, said pin 189 being subject to spring 191 tendii'ig to push it out of said slot or recess. Gear hub 185 is provided with a block or piece 192 of insulatin material against which pin 189 normally presses. During normal conditions no connectionis made with 189 because of the latter being of insulation, but when pin 188 breaks and permits 3 to turn relatively to 7, piece 192 will move away from end of pin 189, thereby permitting the latter to come into contact with. bar 01" metal of gear 185, thereby establishing electrical connection. This connection extends through spring 191 to metal plate 19% having an annular surface 195 on which commutator the brush 196 rests. Thus con .cction made with pin 189 is communicated through spring 191,

plate 195 and brush 196 to the automatic switching and annunciator apparatus which will be presently described. Plate 19 1 is fitted on sleeve member 197 which is made of insulation so as to insulate plate 19 1 and an insulating disk 198 is fitted adjacent plate 19% to insulate the other side of same, whereby pin 189 and connections are properly insulated from the machine. Brush 196 is mounted on bracket 199 by means of screw 209 and conductor 201 is connected to binding screw 200 and let thence to the switch and annunciator apparatus previously referred to.

Referring now to the arrangement by which these various electrical circuit controlling mechanisms control the operation of the machine, IQLQIQDCO is made to Fig. 20. In

- this figure I show the electric driving motor 1 diagrammatically and show it connected with a rheostat 202 by which its resistance and speed are controlled and varied. There is also shown an automatic cut-out switch 203, one side of which is connected by wire 204 with a motor and the other side of which is connected by wire 205 with the rheostat 202, which in turn is connected by wire 206 with the other side of the motor. From automatic switch 203 wires 207 and 208 run to a main switch 209 which is in turn connected by wires 210 and 211 with the outside circuit for supplying energy to the motor 1.

The automatic switch 203 is understood to be normally closed but automatically operable to open the motor circuit 204-205 on passage of current through said switch 203, for which purpose a main wire 212 is shown running to one side of the switch mechanism and a ground wire 2133 running to the other side of the same. l Vire 212 runs to a main battery 214 having ample power to operate switch 203. In place of battery 214 of course some other source of electrical energy could be used.

The various circuit controlling devices pre viously referred to are connected with the automatic switch 203 so thateach one will open the same and thereby stop the driving motor 1, when trouble occurs. Also annunciator mechanism M is present to indicate the place of trouble. Considering first trouble point G,

the feeding of two or more cover sections from stack A, conductor 139 running to contact screw 135 is connected to annunciator magnet 215, whence conductor 216 runs to fuse 217 and thence to battery lead 218 and battery 214 and thence to automatic switch 203 and thence to ground by conductor 213, the circuit being completed through ground and to the other side of the machine 219, so that connection is made through annunciator magnet 215 and automatic cut-out switch 203, thereby actuating said annunciator magnet and indicating that there is trouble at point G and also automatically opening the motor circuit and stopping the motor. The trouble may be located at G and remedied and automatic switch again closed and the operation f the machine resumed.

In a similar manner circuit control mechanism at point H, the left hand or cover section receiving end of the trough, has its conductor 155 running to contact 147 connected to annunciator magnet 220, whence connection is made by conductor 221 to fuse 222, and thence to battery 214, automatic cut-out switch 203 and ground, the other side of the circuit at the machinebeing indicated at 223. In a similar manner trouble at this point will be indicated by annunciator magnet 220 and the motor circuit switch automatically opened to stop the machine. The trouble being located and remedied the machine is again started.

Similarly the circuit controlling mechanism at trouble point I has its conductor 164 running from contact 163 connected with annunciator magnet 228, whence circuit wire 229 runs to fuse 230 and thence to battery 24 and automatic switch 203 as in the case of other connections. Similarly the mechanism at point K, the delivery end of the trough, has its conductor 184 running from contact 182 connected with annunciator magnet 232 which latter is connected by conductor 233 with fuse 234, whence connect-ion is made through battery to automatic cut-out switch and to ground as in other circuits. Also circuit connection at point L, the main drive shaft connection, has its conductor 201 connected with annunciator magnet 235 and thence by conductor 236 to fuse 237, and

thence to battery cut-out switch and ground as in other arrangements. The four circuit closing arrangements at the stacks B, C, D and E, namely at points J, J, J and J have their conductors 17 8 connected respectively with eccentric magnets 240, 241, 242 and 243, and thence by conductor 244 through timer 245 and fuse 246, to battery and automatic cut-out 203 and ground. Timer 245 is included in circuit with these devices in order that the circuit may be closed through these circuit connections only when paper sections are being fed from their respective stacks D, C, etc. At other times the circuits are open, so that there will be no operation in these mechanisms when no paper sections are normally passing out of said stacks. To such end this timer 245 comprises a rotary contact 245 adapted to make contact with a stationary contact 247, the period of contact being the period when paper sections are passing out of said stacks.

In Fig. 16 is shown an arrangement for preventing improper starting of the machine. This comprises a switch having contacts 255 and having a projection or pin 257 passing through switch box 258 and controlled by springs 259 tending to push projection 257 out of box. l Vhen bar 260 is down, projection 257 is depressed, contacting 255 with 256 and closing circuit, permitting the machine to run. lVhen bar 260 is withdrawn, circuit is opened, thereby preventing machine from running. Bar 260 is used to turn ma chine by hand, being inserted in apertures in a wheel not shown on the driving shaft to give leverage to turn the shaft and move the machine little by little for inspection purposes. If bar 260 were left in an aperture in
